Hooper has warning for grand slam rivals

WALLABIES star Michael Hooper has warned rivals that there is plenty of room for improvement in the team as the Australians prepare for two of the most important Tests of the year.

If the Wallabies overcome Ireland in Dublin this weekend they will face England next weekend with the chance to complete Australia's first grand slam of victories over the four home nations in 32 years.

The Wallabies headed to Europe with just three wins from 10 Tests in 2016 but since arriving, that tally has doubled with wins over Wales, Scotland and France.

Hooper said the winning start has been a positive but declared there is still plenty of improvement left in the team.

"(Our) combination is just getting better and better, our attack is starting to really click,” he said.

"We had some shaky starts to the season and our attack couldn't get much points on the board.

"But I think our attack's starting to get really smooth and we're just away from opening up teams, with last passes and getting down into the scoring zone and not being able to convert points, so we're close to really breaking teams open.”
